Figure 1 As shown, the first direction G is defined as the direction in which the shell 51 and the cover 52 are connected. Along the first direction G, the shell 51 and the cover 52 are close to each other and welded together. In other embodiments, the shell 51 and the cover 52 may also be close to each other and then threaded together. The direction of the threaded connection is the circumference around the first direction G. Figure 1-4 As shown, the first flow channel 13 is located on the side of the shell 51 away from the cover body 52, at least part of the first flow channel 13 extends along the bottom surface of the shell 51, along the first direction G, the first flow channel 13 includes two flow channel layers located at different heights, the first layer includes a plurality of parallel flow channels, the second layer includes three branch flow channels, and the second flow channel layer is located on the side of the shell 51 away from the cover body 52 compared to the first flow channel layer.

Both the first sub-channel 11 and the second sub-channel 12 are straight-through channels, and the first sub-channel 11 and the second sub-channel 12 are arranged in parallel with each other, so that the channel path connecting the multi-way valves is the shortest, which is conducive to the compact arrangement of the integrated device 100.

The first connection port 131 and the second connection port 132 are at least partially arranged oppositely, which is more conducive to the integrated device 100 to replenish the circuit including the second pump 82. The housing 51 is also provided with another third sub-flow channel 130 corresponding to the third pump 83, and the structure is similar, which is not repeated here.

[0040] The flow channel layer of the first layer also includes a fourth sub-flow channel 134, at least part of the fourth sub-flow channel 134 is a straight flow channel, and the fourth sub-flow channel 134 is substantially parallel to the first sub-flow channel 11. Specifically, the fourth sub-flow channel 134 includes two, and the two fourth sub-flow channels 134 are respectively arranged at the outermost sides of the parallel flow channels of the first layer.

[0041] The second flow channel layer includes a fifth sub-flow channel 135, such as Figure 1-15 As shown, the fifth sub-channel 135 is connected to the cavity of the mounting portion 18 corresponding to the pump 80.

The projections of at least part of the wall forming the second flow channel 14 and the wall forming the liquid storage chamber 53 on the first surface L overlap. In other words, along the first direction G, at least part of the wall forming the second flow channel 14 and the wall forming the liquid storage chamber 53 overlap. In other words, at least part of the second flow channel 14 is located on the peripheral side of the liquid storage chamber 53. Such an arrangement makes full use of the space on the peripheral side of the liquid storage chamber 53, which is conducive to simplifying the arrangement of the flow channel 10 of the integrated device 100 and facilitating the compact design of the integrated device. The flow channel of the integrated device 100 includes a second flow channel 14 and a first flow channel 13.

Along the second direction S, at least a portion of the wall forming the second side channel 700 overlaps with the projection of the wall forming the liquid storage chamber 53 on the first plane L, or, along the first direction G, at least a portion of the wall forming the second side channel 700 overlaps with the wall forming the liquid storage chamber 53. Specifically, along the second direction S, at least a portion of the wall forming the seventh branch channel 77, the eighth branch channel 78, and the ninth branch channel 79 overlaps with the projection of the wall forming the liquid storage chamber 53 on the first plane L.
